Abstract: Taking the rural power grid loss reduction and energy-saving optimization project in a certain region as an example, combined with the basic situation of the distribution network, this paper analyzes the causes of line loss from two aspects: technology and management, and proposes corresponding solutions. With the aim of reducing losses and increasing efficiency, combined with the actual situation of rural electricity consumption, a loss reduction and energy-saving plan is formulated to comprehensively plan and transform the layout structure, lines, transformer configuration of the power grid. At the same time, management measures are proposed from the perspectives of system structure, technological empowerment, and organization to effectively reduce the high and low voltage line loss rate.
